Extensible Firmware Interface External Graphic Card, Mainframe System, and Extensible Firmware Interface BIOS Booting Method

摘要

A central processing unit of a mainframe system is configured to load a physical graphic card driver into a memory of the mainframe system for performing a display function when the mainframe system is not connected to an Extensible Firmware Interface (EFI) external graphic card. The central processing unit is further configured to load a virtual graphic card driver into the memory of the mainframe system for performing the display function when the mainframe system is connected to the EFI external display card.

主权项

1. An extensible firmware interface (EFI) external graphic card, comprising:
a graphic processing unit (GPU); an EFI graphic card driving module, configured to store an EFI graphic card driver; a connection port; and a control module, configured to enable an EFI Basic I/O System (BIOS) mainframe system to drive the EFI graphic card driving module when the connection port is connected to the EFI BIOS mainframe system, for loading the EFI graphic card driver from the EFI graphic card driving module to the EFI BIOS mainframe.
